The improvement of the speaking and singing voice can be considered as the historical field of application of the Tomatis method.
It was when practising in occupational medicine that Doctor Tomatis came to make the discoveries which now bear his name and which concern the links between phonation and hearing. He demonstrated that it was possible to correct either one of these essential functions.
Tomatis’s first fundamental discovery, called the “first Tomatis law” can be stated as follows: the voice only contains what the ear hears, or to put it differently, ‘the larynx only emits the harmonics which the ear can hear’.
For Tomatis, a quality vocal emission not only requires good listening to the acoustic message coming from the outside, but also and especially good self-listening, that is to say the ability to use one’s own voice as the sound source to be analysed and controlled in terms of accuracy, intensity and quality.
This self-listening is possible provided that the perceived sound vibration is correctly regulated through bone conduction, the transmission of sound by all the bones in the body and in particular by the skull.
This bone regulation itself depends on the harmonious functioning of two muscles situated in the middle ear, whose role is to control and absorb all of the vibrations transmitted to the inner ear.
The purpose of audio vocal re-education under the electronic ear is precisely to implement a mechanism of quality self-control.
Thus, depending on the vocal problem being dealt with, the action of this procedure can focus on:
- The lack or loss of the desire to sing
- Difficulty speaking or singing without feeling a need to force or push the voice
- The lack of verbal fluidity
- The lack of accuracy and precision
- The lack of or the imbalance of timbre, giving rise to voices which are too dull, too high-pitched or too nasal
- The lack of expressivity in the voice, due to an absence of modulation or intonation
- The loss of control over intensity, whether resulting in a voice that is too faint or too loud
